Mono-fibre systems with high density matrix

4 Mono-fibre systems with high density matrix 

The theoretical background and the mechanics concept of such composites was discussed in Section 12.2.2, and in this section the properties reported and the characteristics of different systems will be reviewed. 

A common feature of all of these composites is the dense matrix made of well-graded particles, ranging from about 0.1 fim silica fume to sand particles with maximum size in the range of 0.6-4 mm. In several reports [9,10] the effect of the maximum size of the graded aggregate, up to 8 mm, was evaluated. The main differences in the concept of the different composites in this class is the 

Recommendations for design, testing and evaluation of such composites were developed in France [45]. Using these recommendations, Chanvillard and Rigaud [46] evaluated the tensile and flexural properties of DUCTAL using notched specimens. Elastic-plastic behaviour in tension was observed, up to crack widths 

Lange-Kornbak and Karihaloo [10,50] developed a generalized model to determine the optimum composition and properties for strain hardening FRC,
